Smart heart rate sensors are electronic components designed to measure and track a person’s heart rate in real time. These sensors are commonly integrated into wearable devices such as smartwatches, fitness trackers, and health monitoring systems. Their primary purpose is to monitor cardiovascular activity during daily routines, exercise, and sleep.
The development of smart heart rate sensors is closely linked to the growth of wearable health technology. As digital health monitoring becomes more common, these sensors help individuals understand how their heart responds to activity, stress, and rest.
Most modern sensors use photoplethysmography (PPG), which relies on light to detect changes in blood flow beneath the skin. These changes are converted into heart rate data, enabling continuous monitoring through wearable devices.
Some advanced devices also use electrocardiography (ECG), which measures the electrical signals generated by the heart. While PPG is widely used in fitness trackers, ECG is typically found in more advanced health monitoring systems.
